In my opinion, I was grateful Nanamo didn't die, but at the same time, I have to agree with Fenral on that the potential for radical chance is there but will never be fully realized an I think the fact that 3.0 is not needed for 4.0 is related, (Though I'm not sure if its the cause or the effect of that)
Also I blame the Death of Superman Comic Book arc for the "Death is Cheap" thing happening in media in general
